In this RP, you can do anything you want, as long as you follow a few rules. The universe is a blank slate, and you have just been given the tools to make it more. Destroy it, help it, the choice is yours.

Calynos is an Earthlike planet with one ocean and one continent, the latter of which is divided in half by a huge river. The Skorin occupy the cold Southern Polar Region, their distant relatives the Luminai occupy the desert-covered northern area, and the artificial lifeforms the Argenai, creations of the Luminai, occupy areas near the Dividing River. These three races are the only sentient lifeforms on the planet, though there are many more non-sentient lifeforms. The Skorin were the first sentients, but they were not native to Calynos; they came from another universe. Calynos is the sole planet orbiting a sunlike star far away from Earth.

Needless to say, the little group would have been momentarily blinded by the bright flash of light. When they regained their vision, they would see that their surroundings had vastly changed. Gray metal walls on three sides, and a matching floor and ceiling. Ahead of them, a transparent door, and beyond it, a room full of dark-skinned humanoids. One such being looked in through the door, and waved to the others, shouting in some unintelligible tongue. (Unintelligible to the group, anyway, his comrades obviously understood him.)

"Not only that," The being said, giving them a strange grin, "But if you stay here, when the next guests arrive, the energy surge will rip your molecules apart. Very painful way to die, from what I understand."

(( He's got a translator, built to spec by studying humans, including their language, for several years. They picked out Earth because of it's "popularity" for extradimensional (my definition) and extraterrestrial visitors. As for how they could speak to the twins, since MOST of the Skorin are friends with the Luminai, could it be feasible that the Skorin had studied their race before it went bye-bye? ))

"Come along, please." The alien said. "Kelm-arn Dantai will explain everything." He motioned for the twins to follow, obviously recognizing that they could not understand his speech.
